But your quote supports what Barbelo presented and it doesn't support Trump's action is against the Constitution.
Here is your quote..."Senator Mike Lee My initial assessment is that what Pres. Trump announced is legal. Whether or not it should be legal is a different matter. Congress has been ceding far too much power to the exec. branch for decades. We should use this moment as an opportunity to start taking that power back."
From the quote Senator Lee says his initial assessment is what Trump announced is LEGAL. He questions whether it should be legal and provides why and it has nothing to do with it being unconstitutional.
